The youngest of the Kardashian-Jenner crew raised some eyebrows back in July when she covered Forbes and was categorized by the magazine as a "self-made millionaire." Her financial status can be attributed, of course, to the success of her brand, Kylie Cosmetics, though the idea of her being self-made is still seen as debatable by many. Last year, Kylie was said to be worth $900 million — making her the richest of her siblings — and the recent distribution deal she struck to have her famed lip kits sold exclusively in Ulta stores nationwide is likely what tipped her into billionaire status.
